Is there a way to fix it? Are there working alternatives to Shutter for 17.10?
You should be able to use the default and pre-installed screenshot application without any issue. You can launch it by running
gnome-screenshot -i (interactive mode) in Terminal or simply by searching for "Screenshot" in "Activities".
If it is not installed by any chance, you can install it by running
sudo apt install gnome-screenshot
Once you've captured screenshots using this application, you should be able to open them with Shutter and edit.
